I know a likely workaround, by the way, but that would just leave out whatever partition's going wrong here, and so I want to know why the number's coming out negative. /var/log/partman doesn't seem to show it clearly, which I think means it must be in get_ext2_resize_range around where it calls tune2fs. A shell trace should clarify this.
